The service checks performance, refreshes filtration media where needed, and confirms the system is set up correctly for your household’s water and usage. ## What the service covers A whole-house water filter needs periodic checks and maintenance to keep it filtering properly and to prevent pressure drop, bypass issues, or contamination within the housing. Servicing is tailored to the type of system installed and local water conditions. - Visual inspection of the filter unit, pipework, valves, and fittings - Check for leaks, corrosion, and signs of bypass or incorrect flow direction - Pressure and flow checks to identify blockages or media that is nearing end of life - Replacement of cartridges or filter media where required (system dependent) - Cleaning and sanitising of housings where appropriate - Confirmation of settings and operation, including isolation and bypass valves - Clear recommendations on service intervals and any upgrades if performance is limited ### When this service is a good fit This service is ideal if your water has started to taste or smell different, your flow rate has dropped, or you are seeing more limescale and sediment than expected. It also suits landlords and small commercial sites that want predictable maintenance and fewer call-outs. If you have recently moved into a property, a service helps confirm the filter is safe, effective, and correctly specified. ### How the service is carried out The visit starts with a quick assessment of the existing filter type, installation condition, and how the property uses water. The system is isolated, then key parts are checked, cleaned, and refreshed as needed, with care taken to protect your pipework and water supply. Before completion, the filter is brought back online and tested to confirm correct operation and normal flow. ### Ongoing performance and next steps You will be advised on realistic service intervals based on local water hardness, household size, and the filter specification. Where a system is undersized, incorrectly installed, or no longer supported, you will get practical options for improving performance. Regular servicing helps maintain consistent water quality and reduces the risk of unexpected leaks or restrictions.

Most systems benefit from a routine service every 6 to 12 months, but it depends on your water quality and usage. If you notice reduced flow, odours, or more scale, it may need attention sooner. Will a whole-house filter remove limescale? Standard sediment and carbon filters do not usually remove hardness minerals that cause limescale. If limescale is the main issue, you may need a dedicated scale reduction system or a softener, and the setup can be assessed during the visit. Can servicing improve low water pressure? Yes, clogged cartridges or exhausted media can restrict flow and cause a noticeable pressure drop. Servicing can identify whether the filter is the cause or if there is another issue in the system. Do I need to turn off the water during the service? The water supply is normally isolated briefly while the housing is opened and components are changed or cleaned. If your system has a bypass, disruption can often be kept to a minimum. What if my filter system is old or parts are no longer available? The system can still be assessed for safety, leaks, and performance. If parts are obsolete, you will be given clear replacement options that suit your property and the results you want from filtration.
